Vehicle-mounted drunk-driving-prevention system

Abstract

The invention relates to a vehicle-mounted drunk-driving-prevention system. The system comprises a microprocessor, a pyroelectric human body infrared sensor module, a GPS positioning module, a driving module, an alarming module and an alcohol concentration detection module. The driving module is connected with a car engine supervisor. The pyroelectric human body infrared sensor module and the alcohol concentration detection module are both arranged on a car steering wheel. The GPS positioning module is arranged in an engine. The alcohol concentration detection module comprises a single chip microcomputer, an alcohol sensor and a digital analog converting module. The microprocessor comprises a data storage unit, an alcohol concentration determining unit, a control unit and an information interaction unit. The data storage unit is used for storing an alcohol concentration threshold value. The alcohol concentration determining unit is used for determining the concentration of alcohol in gas exhaled by a driver. The control unit is used for controlling the driving unit. The vehicle-mounted drunk-driving-prevention system is good in reliability, high in practicability and recognition capability and capable of effectively preventing drunk driving, lowering traffic risks and greatly improving the life safety of the driver and pedestrians.

Description

technical field [0001] The invention belongs to the technical field of automobile safety, and in particular relates to a vehicle-mounted anti-drinking driving system. Background technique [0002] With the increase in the number of cars, drunk driving is also increasing, and drunk driving is one of the important reasons leading to traffic accidents. International research results show that 23% to 66% of single collision injuries are caused by drinking and driving. Drivers "drunk driving" and "drunk driving" are very prone to road traffic accidents, seriously endangering road traffic safety and the safety of people's lives and property. [0003] In order to crack down on drunk driving, it is mainly through the detection of traffic police on the road, but the detection of traffic police on the road cannot be detected, and it consumes a lot of manpower and material resources, and it cannot completely avoid the occurrence of drunk driving. Mainly, but many people still have lu...
